Question

The emitter base junction of a given transistor is forward biased and its collector base junction is reverse biased. If the base current is increased, then its.

• A. $V_{CE}$ will increase
• B. $I_C$ will decrease
• C. $I_C$ will increase
• D. $V_{CC}$ will increase

Answer 1

The correct option is C $I_C$ will increase

The base current causes things to happen in transistor;a proportional amount of collector current flows.So changes in base current are amplified into larger changes in collector current.

$I_c=\beta I_b$

collector current is directly proportional to base current,

hence if base current is increased $I_c$ will increase
